Bloomingdale/LeDroit ParkPervious Paver and Impervious Surface Removal Rebate Overview

Who is Eligible: Any single family home, multifamily property, commercial, institution, house of worship or educational facility is eligible including homeowners who have already received funding through the RiverSmart Homes program. There is a limit to one rebate per property. The property must be within the Bloomingdale/LeDroit Park boundary (http://ddoe.dc.gov/service/bloomingdale-sewershed-rain-barrel-cistern-program). Rebate Structure: The rebate is based on area of impervious surface removed and replaced with permeable pavement or vegetation. The rebate for permeable pavement is $10 per square foot with a maximum rebate of $5,000 per property. The minimum square footage that you must treat is 50 square feet, which would total a $500 rebate. The maximum rebate is $5,000 or treating 500 square feet or more of impervious surface. A downspout or rain barrel/cistern overflow must be extended into the permeable pavement to increase treated area. The rebate for impervious surface removal with a conversion to vegetated space is $5 per square foot with a maximum rebate of $2,000 per property. The minimum square footage that you must treat is 50 square feet, which would total a $250 rebate. The maximum rebate is $2,000 or treating 400 square feet or more of impervious surface. A downspout extension is not required to convert impervious surface to vegetated space. Funds are limited, so rebates will be awarded on a first come first served basis.

Project Implementation: For removal of impervious surface you may either perform the work yourself (DIY) or hire a contractor. Please note that the Pervious Pavement Installation must be completed by an ICPI certified contractor (http://www.icpi.org/certification) and cannot be DIY. For a list of contractors please visit the ICPI website (http://www.icpi.org/directory-search?search=contractor) or contact sdavidson@allianceforthebay.org – it is recommended to seek at least three estimates.

Steps to Complete Before Project Construction (you or your contractor must complete these steps):

Perform a Perc Test (see the Perc Test Worksheet) – necessary for Permeable Pavement only

Put together a Site Design for project construction and estimated project cost (see Site Design Guidelines for your project type)

Submit your Site Design, Perc Test Worksheet, and Pre-Construction Checklist to Sarah Davidson at sdavidson@allianceforthebay.org, or mail to 501 Sixth Street, Annapolis, MD, 21403, or fax to 443-949-0673

Pre-construction inspection by DDOE or Alliance for the Chesapeake Bay

You will receive pre-construction approval to begin construction (if your project needs revisions you will be notified). Construction must be completed within 4 months of the date of the Pre-Construction approval notification. Once the work is completed, notify Sarah Davidson at sdavidson@allianceforthebay.org or 202-817-9672 to schedule the post construction inspection.

Site Design Guidelines Check list for Impervious Surface RemovalThe area where impervious surface is removed must be vegetated. The exposed soil must be tilled or mixed so that it is no longer compacted, and either sod or plant material must be installed. Edible gardens are permitted. We encourage the use of native plants; visit http://nativeplantcenter.net/ for more information on native plants to the Chesapeake Bay.
